Answer:
<em>0.15</em>
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
<em>Hence the airplane is flying at 0.15</em>
Answer:
y=7* (0.5)^x
Step-by-step explanation:
We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.
i.e. when x=a and x'=a+2.
then y/y=0.25 where y' is the function after putting x' to the old function.
